Theobject of this invention is.to provide a door securerin the form of a 'ri'gid'prop that will act as a supplemental holding means, or second line of deie'nse, in case the main door lock, or first line" of defense,ha s been.

broken or outflanked;

A special object of the nventi'on 1s to provide asupplemental door secu'rer that will allow'the door tomove a limited distance after the main securing means has been over come and will then come into operation to rigidly hold the door against further movement. The door is permitted to have this limited amount of lost motion in order to;

permit the operation of a burglar alarm system' as fully set forth in my application Serial No. 586,573, filed on September 1922, of.

which this is a division.

On the chief features of this invention 1s 2 the fact that the brace rod forming the supplemental stop is concealed and protected behind the door even when the door'is in its second protective position. i IVhile I have disclosed a preferred embodiment of the invention for purposes of illustration, it should be understood'that various modifications could be made without departure from. the spiritand scope of the invention as hereinafter defined and claimed. In the drawings: a Fig. 1 is an elevation partly'in sectlon showing the invention applied to a door;

Fig. 2 is a plan view partly broken away showing the means for locking the upper end of the brace rod; Fig. 3 is a section on line 33 of Fig. 2; Fig. 4 is a plan View of the floor plate; Fig. 5 is a detailed view showing the cooperation of the brace rod with the floor plate; l

. Fig. 6 is a detail of a modified brace rod. In the drawings the'door 10' is provided with a supplemental holdingmeans including the brace rod 11. The lower end of this 5 rod fits into an opening 12 formed in the floor plate 13 and is slotted at 1 1 to enable the rod to ride into the key-hole slot 15 formed in the floor plate.

The upper end the lock casing 16 secured to the door.

sliding bolt 17 is mounted in the casing and is supported by a shoulder 18 of the casing.

f the brace rod extends into Oneend of the bolt'is provided with a cradle 19 adaptedto receive and guide the upper-end of the brace roan.-

' The sliding bolt is oscillatedby a-cranlrpin I V 20 carried by a conventional lock. barrel 21, and cooperating with. a notch 22 formed; in the upper surface of the bolt. i p

The casing 16 is formed with a guideway 23 near itscenter, and carries a rigid abutment. 24e' o'n one side of the guideway. I .11 guard yoke 25 is locatedjust below the abutment 24,

while a similar yoke 26 is located at the upper I end of the guideway 23.

When the brace rod is engaged in the floor plate, and the sliding bolt 17 holds the upper,

end of the rod under the abutment 24,

shown in Fig. 2, the parts are in protective position. If an intruder should force. the main lock'of the door and attempt to push the dooropen, the brace rod would contact with the abutment 24 after allowing the door to move a slight distance to take up the space normally left between the rod and the abutment as seen in Fig. 2. The brace rod would.

then form apositive stop to prevent further j opening of the door. 1

When an authorlzed person wishes to open the door, he operatesthe lockbarrel to move the rod into registry with the guideway 23. As the door is opened the rod will slide into the guideway to the dotted line position of Fig. 1, permititng the person to enter.

In the modification shown in Fig. 6 thelower end of the rod is provided with a sleeve 27 housing a spring 28 and guided by a slot 29 moving over a pin 30 carried by the rod. 1

This means may be used to provide additional lost motion at the lower end of the rod.

It will'be clear that this supplemental door holding means permits a limited opening of the door before it comes into play to positive- 1y hold the. door. The holding means comprises a rodthat is concealed and protected at all times, and hence an intruder cannot gain access to'cut or remove it. I

W'hatI claim is: r

1. In apparatus of the character disclosed, securing means 'operatively connected to a door, lock-controlled means for moving said securing means toprotective position, said securing means being arranged to allow a lim-'. ited opening of the closeure before becoming operative.

2. In apparatus of the character disclosed,

3. In apparatus of the character diselosed, a brace rod adapted to engage an abutment Secured to the floor, a look easing carried on the door and adapted to receive the brace rod-,a guideway in the casing and an abutment in thecasing, and a sliding bolt for moving the upper end ofthe brace rod from alinement with the guideway into llimment With the abutment.

4. In apparatus of the character disclosed, a brace rod adapted to engage an abutment secured to the floor, a, lock casing carried on the door and adapted to receive the brace rod, a

gnideway in the-easing and an abutment in the casing, end a lock-controlled belt for moving the upper end of the brace rod from alinement with the guideway into alinement with the abutment.

I11 pparatus of the charmer is a, brace rod adapted to engage an abutment secured to the floor, a lock casing carried on the door and itdnpted to receive the brace rod, a guide way in the casing adapted to perwit the rod to slide therein to allow opening of the door by an authorized person, a stop in the casin ands lok-eofitfofled'bolt slidably mounted in the casing and having a part receiving the rod, thf bolt being adapted to move the upper and o the rod fromfail'ifieiiient with the g ideway to alineinent with the stoii, the parts being arranged to provide auspprecieble spaee between the end of th grod and the stop when the is in pnsitibn a ilid "i i-" h i Hi1; 5;;
